Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512818, here are decompositions:

71 + 512747 = 512818
101 + 512717 = 512818
107 + 512711 = 512818
197 + 512621 = 512818
227 + 512591 = 512818
239 + 512579 = 512818
281 + 512537 = 512818
311 + 512507 = 512818

Showing the first eight; more decompositions exist.
